A kind of vinyl cover has outer peripheral edges (4) that surround a barrel neck (3) and one and extend into a barrel wall (3) and protrude in the inner peripheral (5) that covers at the end (6) below bung, also has a seal ring that is embedded between bung outer peripheral edges (4) and the bung inner peripheral (5).The sealing circle is pressed on the opening periphery (14) of a barrel neck (3) by a tightening hoop (10) or tensioning steel wire, and annulus (7) bottom that is formed by bung outer peripheral edges and inner peripheral (4 or 5) is provided with an outstanding vertically annular baffle (8).This dividing plate will be because of piling up when closing lid (1), and the axial force that situation such as fall forms is directly delivered on barrel neck (3).

Description

The vinyl cover of blow molding Plastic Drum
The present invention relates to a kind of vinyl cover of blow molding Plastic Drum.This lid has outer peripheral edges that surround barrel neck and one and extend into barrel neck and protrude in the inner peripheral that covers the end below bung, also has a seal ring that is embedded between bung outer peripheral edges and the bung inner peripheral, the sealing circle is the opening periphery that is pressed on barrel neck by a tightening hoop or tensioning steel wire, and wherein one of tightening hoop or tensioning steel wire overlap joint is positioned on the bead or some bead sections below the bung outer peripheral edges.And clamp a radially outstanding solid edge equidistant with the bucket wall below bung outwardly, this edge is to make annular flange or be divided into bead section at interval.
A kind ofly need pass to accumulation force and the axial impact force that produces this moment on the edge of bucket by the outer bead that is arranged on the bung lower rim by the known lid bucket that connects of Germany patent specification DE2544491 C2, form very big moment of flexure simultaneously, so just make bung bead and/or barrel edge and tightening hoop that the danger of damage is arranged, cause barrel blowing-by and can not use.
Task of the present invention is, proposes the vinyl cover that a kind of reliability of service is improved.
The technical scheme that solves task of the present invention is, be provided with an outstanding vertically annular baffle, the axial force that forms owing to reasons such as accumulation, whereabouts during with closing lid is directly delivered on barrel neck, above-mentioned annular baffle is outstanding vertically from the annulus bottom of bung outer peripheral edges and inner peripheral formation, to the both sides of annular baffle configuration seal ring, these seal rings lie on the opening periphery of barrel neck to give stress when closing lid.
Further architectural feature of the present invention is as described below: with tightening hoop leak free situation, its bead has a spacer segment mutually when bung is closed for this.Seal ring is that prefabricated back embeds.
Its advantage excrescence of vinyl cover of the present invention is following now described:
In the xial feed that is subjected to stack load and takes place suddenly, for example under the situation about falling from eminence, one is not transshipped, from but the sealing of stepless action, load is just directly passed on the ladle bowl through bung, so not only make the outer bead on the bung lower rim, but also make the edge of bucket bear flexure stress.The bung sealing arrangement goes for coming the leak free bucket by tightening hoop or tensioning steel wire.Because it is always certain to give stress in the seal ring, so will prevent the fatigue of sealing ring material, makes it have durable sealing function.If the damage that seal ring of a plurality of leak frees meets accident then still guarantees sealing by second seal ring.
The present invention adopts tightening hoop leak free and such employing tensioning steel wire leak free wide mouth drum to describe by means of following accompanying drawing to one.Wherein
Fig. 1 and Fig. 2 represent a bucket neck region of adopting the tightening hoop sealing and having the wide mouth drum of annular barrel edge, and Fig. 1 represents to be in open mode, and Fig. 2 then represents to be in closure state,
Fig. 3 represents a same bucket neck region with bucket of discontinuity edge,
Fig. 4 represent a bucket neck region of adopting tensioning steel wire leak free wide mouth drum and
The various embodiment of Fig. 5 to 12 expression bung leak free.
One covers wide mouth drum 2 as depicted in figs. 1 and 2, and with the bung 1 of plastic injection-moulded shaping, it has the outer peripheral edges 4 and the inner peripheral 5 that extend into barrel neck 3 that surround barrel neck, and this inner peripheral is positioned at below the bung, and protrudes in and cover at the end 6.Bung outer peripheral edges and inner peripheral 4,5 forms an annulus 7, annular baffle 8 of projection vertically from its bottom.Press Fig. 1, the sealing material 9 of bi-component is injected in the outside of this annular baffle 8, such as the polyurethane that has hardener.
With the closed bung 1 of a tightening hoop 10 time, this of tightening hoop overlap joint is positioned at the annular flange 11 below the bung outer peripheral edges 4, and clamping one is positioned at below the bung and the radially outwardly outstanding solid edge 12 equidistant with the bucket wall, annular baffle 8 will seal material 9 and be divided into two seal rings 13, in order to compress the opening periphery 14 of barrel neck 3, wherein seal ring 13 is stretched in (Fig. 2) on the opening periphery 14 in advance.When closed tightening hoop 10, bead 11 does not contact with edge 12, and the axial force that acts on like this on the bung 1 just directly is transferred on barrel neck 3 certainly, thereby is transferred on the staving 2.
Fig. 3 illustrate be applicable to a kind of wide mouth drum 2 ' same bung 1, this moment the edge be the mode of making some bead sections.
Fig. 4 represent a kind of bung 1 that is applicable to the same sealing arrangement of wide mouth drum 2 ' have ', this wide mouth drum have the edge 12 that is divided into some bead sections equally '.A kind of be used for closed bung 1 ' tensioning steel wire 15 clamped edges 12 ' some bead sections and overlap those and be positioned at bung outer peripheral edges 4 ' some following bead sections 16, bung outer peripheral edges 4 ' the pass interval between edge 12 ' some bead sections wherein, edge 12 ' some bead sections and bung outer peripheral edges 4 ' some bead sections 16 then form the wedge-like areal of support of tensioning steel wire 15.
Press some the sealing arrangement embodiment shown in Fig. 5 to 12, two seal ring 13 is interconnective by a connection thin plate 17.Represent to each have the bung of a band shape dividing plate 8 by the embodiment of sealing arrangement shown in Fig. 5 to 8 and Figure 10 to 12, this dividing plate has an areal of support of widening 18.By its areal of support 17 of sealing arrangement shown in Figure 9 is by the decision of the width of annular baffle 8.
In addition, Fig. 5 to 12 illustrates the various structures that may be provided with of the bucket neck edge of opening of supporting ring 13 or its connection dividing plate 17.
Obtain mazy bung 1 or 1 ' sealing by a kind of moulding such as profile of tooth (Fig. 8) or waveform (Figure 10) opening peripheral structure.
